The Tampa Police Department is having trouble getting officers to volunteer to provide security for Beyonce’s upcoming concert, following the pop singer’s controversial Super Bowl halftime performance of “Formation,” which many critics have argued is anti-police.

Typically, off-duty officers volunteer to work concerts and sporting events for the extra income, but none have signed up to work security for Beyonce’s April 29 concert at Raymond James Stadium, which is expected to sell out, a local Fox News affiliate reported.

Police spokesman Steve Hegarty couldn’t say whether the lack of signups signaled officers’ anger toward Beyonce, but explained that the department still has “plenty of time to fill those slots.”

“We’re going to staff it because we have a responsibility to do that regardless of how controversial it might be, who the artist might be, or the politician might be,” Mr. Hegarty explained. “This is a couple of months away, so we’ve still got plenty of time to fill those slots.”

Tampa Police did not clarify if officers could be forced to work the concert or if officers already on duty that night could be reassigned to cover it, Fox reported.

Law enforcement officers and unions across the country have spoken out against Beyonce’s Black Panther-inspired halftime performance and her “Formation” music video, which invokes imagery of the Black Lives Matter movement.

Sheriff Robert Arnold, of Rutherford County, Tennessee, cited Beyonce’s video and her performance during a press conference Tuesday after shots were fired at his home Monday night, essentially blaming the pop star for the recent rise in police officer deaths nationwide.
